Um no.
Do a little bit of research on DOHC, SOHC and OHV engine and you'll discover that's a little bit of a silly question.
The only bolt on DOHC head you could bolt to a K motor is the 130E (happy Irokin! :)) head, its commonly referred to round here as a 3k-r, but you've got more change of retro fitting an RB26DETT head than FINDING one of those, ie forget it. :(
and you say you're not allowd to drive a modified car. ;) How is a head swap any different to the 3 C's!?
